[keycloak-user] Galera Replication and Caching

[Marek Posolda]

Which Keycloak version are you using? If it's older than 1.9.8.Final, 
then it's suggested to upgrade as there were caching fixes meanwhile.

There is also possibility to disable caching in keycloak-server.json (or 
in standalone.xml in latest version). It's mentioned in the docs how to 
do it.

Finally it may also help if you have opportunity to try with 2 Keycloak 
cluster nodes configured against same DB node. This may help to better 
isolate the problem and see if it's related to caching or to MariaDB 
cluster.
